Development Board
Howdy Ya'll... I'm an official newbie (but experienced developer), and want to sink my teeth into this tech.
Couple questions for the folks in the know...
1. From your experience... What is best development system to use? And HW requirements? I kinda hate working on Win10, cause if it's not one driver that's missing, it's another. So typically use my trusty Mac and Linux. But if gotta use PC... then well then okay. But what do seasoned developer's use for RealSense?
2. My end application is wearable tech, so what is the best low power board to run the 400 series, and SW dedicated to AR application? RPi? Joule? Other?
A bazillion thanks.... :)

You can certainly use MacOS. MacOS support for the D435i camera model is on its way and there is initial support for the T265 Tracking Camera (which lacks depth sensing and is used, on its own or paired with a depth camera, for achieving very high quality tracking data).
If your application is wearables and you are developing in MacOS then I recommend the D435 (without the 'i') as it excels at applications where objects / people / vehicles are in motion thanks to its fast shutter. It can even handle cars moving at full speed and works excellently outdoors. The D435i is a D435 with an added IMU (accelerometer and gyroscope).
For the newest RealSense models with the latest technology, PC support tends to come first and MacOS later. The current recommended MacOS version for the RealSense SDK development software is High Sierra 10.13.2, though the MacOS installation instructions were recently updated to work with Catalina.
The majority of RealSense developers use Windows or Linux. Using MacOS certainly is not an invalid choice. Judging by the balance of reported specifications on the RealSense forums, there are simply fewer Mac developers compared to the proportion of Linux and Windows developers. Mac users usually prefer to stick with Mac though!
Installation instructions for the SDK on MacOS are in the link below so you can see what is involved.

Once you have prototyped your application on D435, you could consider a caseless D430 Module Kit circuit board (a D435 without the casing or RGB color) for the end product, or save money now by getting a D430 board from the start if you are confident with handling boards.
If you will be using a caseless board and will need RGB color, I recommend the D415 Depth Module, the only board with an RGB sensor built in. It has a slower shutter but can still handle human walking pace motion.
Joule is now a retired product. Raspberry Pi 4 (with USB 3 and desktop performance at a low price) may suit your needs. Nvidia Jetson Nano is another candidate for a small board that works with RealSense.
The 400 Series cameras should work with any Intel or ARM processor though as they are extremely flexible in regards to hardware requirements. The open source SDK software is also designed to run on as many different kinds of computing device as possible, even very exotic ones hardly anyone has heard of. So there is plenty of choice in regard to computing boards for your application.
